Cork, Ireland: Submarine Cable Landing Point

Cork is the second-largest city in the Republic of Ireland, situated in the province of Munster on the country's southern coast. As a submarine cable landing point, Cork connects Ireland to a transatlantic corridor reaching both Canada and the United Kingdom via a single submarine cable. This positions Cork as a node on an intercontinental route linking Western Europe to North America, with an additional regional leg connecting Ireland to its nearest neighbour across the Irish Sea.

One submarine cable currently lands at Cork: the EXA Express. While Ireland as a whole hosts 16 submarine cables across 14 landing points, Cork's single cable places it among the majority of Irish landing points that serve a focused, single-cable function rather than acting as a multi-cable hub. The EXA Express nonetheless represents a meaningful transatlantic connection, extending Cork's reach across more than 4,600 kilometres of submarine infrastructure.

Cables Landing at Cork, Ireland

EXA Express is a submarine cable system spanning approximately 4,600 kilometres, with a Ready for Service (RFS) date of 2015, listed under draft status. The cable connects Ireland to Canada and the United Kingdom, forming a transatlantic link between the British Isles and the North American continent. Cork serves as the Irish landing point on this system, with the cable's other terminations reaching across the North Atlantic to Canada and eastward to the United Kingdom.

Regional Context

Within Ireland's submarine cable geography, Cork ranks alongside several single-cable landing points including Ballinesker, Ballygrangans, Castlefreke, and Clonshaugh, each of which also hosts one cable. Dublin leads the country with three cables landing at a single point, while Kilmore Quay hosts two. Cork's position in the lower tier of Irish landing points by cable count reflects a pattern common across Ireland's 14 landing points, where most locations serve a targeted routing function rather than aggregating multiple systems.

Network Role

Cork functions as a single-cable terminus on the EXA Express system, enabling a direct transatlantic connection between Ireland, Canada, and the United Kingdom. The cable's 4,600-kilometre length places it well above the Irish average cable length of 2,025 kilometres, underscoring its intercontinental rather than purely regional character. Rather than aggregating multiple cable systems, Cork's role is defined by this one long-haul route, providing a western Irish terminus on a corridor that spans the full breadth of the North Atlantic.

Within the broader Irish submarine cable graph, Cork's single transatlantic landing point contributes to geographic diversity across the country's 14 landing points, distributing connectivity beyond the dominant hub at Dublin and ensuring that Ireland's transatlantic cable infrastructure is not concentrated at a single coastal location.
